Between 2000 and 2010, manufacturing output of computer and electronic products rose at a remarkable rate of almost 18 percent per year.
Over the same period, output in the rest of U.S. manufacturing remained roughly flat, according to Bureau of Economic Analysis figures tallied by Houseman. That’s a dismal showing for a decade.
It is only when computer and electronic products are included that overall manufacturing output registers the impressive increases. Though it represents 15 percent or less of manufacturing output, the sector’s strong growth makes the rest of U.S. manufacturing seem much more robust than it really is.
At the same time:
…much of the nation’s production of computers and electronics has moved overseas. The number of consumer electronics shipped from U.S. factories dipped about 70 percent between 2000 and 2010, according to the Census Bureau’s Current Industrial Report.
…at least some of the productivity gains shown in U.S. computer manufacturing reflect the increasing power and decreasing prices that come with innovation. When a computer chip doubles in efficiency, that can turn up in a doubling of output and productivity in computer manufacturing. But that is not what is ordinarily thought of as manufacturing efficiency.
The article is here. It also makes the point that a lot of measure manufacturing productivity gains are actually the result of offshoring, not actual higher productivity in U.S. factories; “This bias may have accounted for as much as half of the growth of U.S. manufacturing output from 1997 to 2007, excluding computers and electronics manufacturing, Houseman and her co-authors have estimated.”
I thank Brent Depperschmidt for the pointer.
